I don't think I've ever seen the current rating of crimps explicitly stated either. Would it be unreasonable to assume it would be no less than that of the maximum cable it could accommodate (at 70 deg say for PVC insulated crimps)?

Well, you'll be working to BS 7727 won't you Zeeps - so this bit will be familiar to you:

7 Current ratingCurrent ratings are dependent upon the conductors in use, the environment and the permitted temperature rise. Correctly designed copper compression terminals and splices, correctly applied to annealed high-conductivity copper conductors will have at least as high current ratings as those conductors. However, with disconnect connectors, which are made from copper alloy, the current ratings are governed by different criteria and advice should be sought from the supplier or manufacturer.

The crimps will either have markings on the palm or barrel or provided in/on the packaging - these will relate to the conductor size and limiting temperature rise.

As I said, typical 6.0mm2 crimps (yellow) will be about 48A when operating to 85C

As was noted the rating basically matches the cable size, at one time there were crimp terminals rated at 50V for automotive applications and crimp terminal rated at 415/240V but I suspect that now because of tooling costs it is much more economical to make one type to suit all.

In the eighties crimp terminals were starting to be used in their abundance in place of conventional termination methods and in order they could be used in the nautical and aviation field they needed to be certified by Lloyds, so the R & D Laboratory at County Wakefield, Ireland was given the task of testing crimp terminals and the tests were;

So the moral of the story is if the crimp terminals are not going to be subjected to temperatures in excess of the above and you are not going to hang your washing on the cables then there is no problem.

Whilst crimp terminals have been deemed an excellent method of termination there are a couple of down sides which are attributed to installation methods and not the crimps, the first one is termination in most cases where crimps have failed is because conductors have been scored when stripping the cable and any lateral movements have caused slight fractures and the second one being the incorrect tools like sidecutters, pliers etc have been used instead of the proprietary tools which apply a set number of crimps at the correct place with the correct minimum torque.

Have you got a calibration certificate for your crimping pliers.
